We have no way of knowing exactly how your baby is doing...
With this pregnancy I didn't get any prenatal care until 22 weeks , any my baby was healthy from the looks of the sonograms . You should be fine !
More then likely yes . I'm on my second child and I haven't done anything but take prenatal vitamins. Just make sure your taking in enough water, protein, and calcium. Oh and enough rest but you should be fine and baby moving kinda gives you a peace of mind. They will run everything at appointment and you should find out what's in there. Exciting! !!! Congratulations
